Can anyone advise if Jack Spade Messenger bag would be ideal for my 15" PB? Link Here I know there are various other bags out there for half that price, but this one is too fitting with a minimalist look. I hate all kinds of zippers and buttons, as it is the case with Brenthaven made ones. So does anyone actually own one of these? Would you recommend it for a 15" PowerBook? Thanks for help.
